package com.newland.util;  import android.app.Activity; import android.view.View; import android.view.inputmethod.InputMethodManager;   public class IMEUtil {    public static void hideIme(Activity context) {   if (context == null)    return;   final View v = context.getWindow().peekDecorView();   if (v != null && v.getWindowToken() != null) {    InputMethodManager imm = (InputMethodManager) context.getSystemService(Activity.INPUT_METHOD_SERVICE);    imm.hideSoftInputFromWindow(v.getWindowToken(), 0);   }  }      public static boolean isSysKeyboardVisiable(Activity context) {   final View v = context.getWindow().peekDecorView();   if (v != null && v.getWindowToken() != null) {    return true;   }   return false;  } }
